I want to preface this post with I have not worked with a charge controller before so there's a couple of questions in general as well as specifics about the chip.
The design I'm working on contains solar panels to charge 3 Lithium-Ion batteries in series that will be connected to various loads
1. In the datasheet, Figure 14. I want to be sure my assumption is correct in that, if the chip detects an overcharge, it will disengage the charge line, but will still allow the batteries to discharge. Then for an undercharge, the discharge line will disengage, but the battery will still be able to be charged. Is my assumption correct?
2. I'm a little lost on the connections of the PACK(+) rail and the CHG(-) and DSG(-) rails. Attached is a crude block diagram. With this design, the load will be able to draw voltage from the solar panels when they are active or from the battery when they are inactive. So "Net 1" would be connected to the PACK(+) rail. "Net 2" would be connected to the DSG(-) rail. "Net 3" will be the connections to VCX. Lastly, "Net 4" will be the CHG(-) rail. Is this how the chip would work?
3. Since we are only using three batteries in series, then the most positive battery will be connected to VC7 and the lowest will be connected to VC9, with VC1-6 tied to VC7. Is that correct?
